Hello chewy,
I hope you will understand that the AdWords team can not turn over an AdWords account lightly - and they must have proof positive that the person who wants access has a legitimate right to have that access. ;)
That said, you will most likely be able to get access to the account if you have, say, precise details as to past payments.
On the other hand, if you have no information about the account whatsoever, it'll probably be a very tough road to gain access - and, I hope that most folks would agree, this is how it should be.
As you note, contacting support is different now than it once was. Given the very high volume (and very broad range) of support requests that come in, the support 'flow' is now designed to filter your request by topic so that it more directly reaches the right team. In your situation, I'd suggest starting on this page:
How do I contact Google AdWords? [
adwords.google.com...]
Once there, follow this path:
Start here > Account Administration (click the plus box) > Login Problems > Why can't I sign in? > No, I don't have my login email address, password, or my customer ID > complete this form
Below, with luck, is the "Why Can't I sign in?" page from the above path. If it does not work for you, then please try following the entire path above.
